Question

Mention any two advantages of a food web as compared to a food chain.

Answer 1

• Food web is the interconnection of different food chains which correlate at various trophic levels operating in an ecosystem.

• Each organism is generally eaten by two or more other kinds of organisms.

• They inturn are eaten by several other organisms.

• So, instead of a straight line the relationship is in series of branching lines hence, creating a food web.

• Whereas, a food chain is a linear network of living organisms in a community through which energy is transferred in the form of food.

• It describes the relationship of organisms about who eats whom.
